The use of precise time for both absolute time tagging and synchronous data
sampling applications offers significant opportunities towards the enhancement
of overall power system performance. The Model 1698E Satellite Timing Unit
makes this capability available in a configuration designed specifically to
address the critical demands of power system applications.

The Model 1698E derives absolute time information from reliable NAVSTAR
Global Positioning System (GPS) satellite transmissions. The Global
Positioning System is a worldwide navigation and timing system which is rapidly
becoming the electric power industry's preferred time coordination medium.

Operation

Several unique features have been incorporated into the Model 1698E to
satisfy the demanding requirements of the power system environment. Clock
synchronization signals (and time codes) are available on electrical
outputs. The instrument also supports the standard IRIG-B format
time code as an output. To provide unattended year round operation the
clock can be programmed to automatically adjust for local time changes
throughout the year. The Model 1698E can be powered by a DC station
battery voltage and is SWC tested to meet the most demanding substation
performance requirements. The Model 1698E is designed and developed by
Macrodyne, a name synonymous with innovation, reliability and performance within
the electric power instrumentation industry.
